kmock javascript 单元测试代码_javascript技巧

复制代码 代码如下:

(function () {
var KMock = window.KMock = function () {

}
KMock.prototype.setup = function (methodName) {
var instance = this;

instance[methodName] = {
returnAs: function (fn) {
instance["_" + methodName] = function () {
instance[methodName].invokeNum++;
fn.call();
}
},
isVerify: function (exceptNum) {
if (exceptNum != null) {
return exceptNum == instance[methodName].invokeNum;
}
else {
return instance[methodName].invokeNum > 0;
}
},
invoke: function () {
instance["_" + methodName].call();
},

invokeNum: 0
};
return instance[methodName];
}

})();

//自己写了个mock类，暂时是用来模拟函数，然后判断函数的调用次数，以下是用法

});
